常识（6）- PowerBuilder的error对象及error.number列表
The Error object is used to record execution-time errors. You can access the Error object from a script (typically in the SystemError event) to learn which error occurred and where it occurred. You can also customize your own version of the Error object by defining a class user object inherited from the built-in Error object.
